Effect of moisture in coal on station heat rate and fuel

The effects of moisture in coal on the power block (boiler-turbine-generator unit) are decreased in boiler efficiency (Figure 7), decreased overall unit efficiency (increase in heat rate) (Figure 8) and decrease in unit load.. The boiler efficiency decreases due to increase in moisture and the unit heat rate increases. This results in increased cost of generation.
